EC, you should take up on LGO's offer, that's a very good application, it may be a little overwhelming, but I think with your passion in logo design, you will be able to figure it out. I suggest you also get a book at your local book store or amazon.com to help you get into the program. There is still plenty of time before OOTPBM2006 is released, just enough to pick up a new hobby, don't you think?
As for the logos above, I like the blues one. It's very neat and clean looking.
Keep on the good work!
